The free-to-total PSA ratio is a calculation derived from two measurements of prostate-specific antigen in the blood: the portion that circulates unbound, or free, and the total amount present. Because benign and malignant prostate tissue can release PSA differently, comparing the free fraction against the total can add context that the total PSA value alone does not provide.

About Prostate-Specific Antigen (PSA), Free-to-Total Ratio in Wheaton

This test reports the proportion of PSA that is unattached to binding proteins, expressed as a percentage of the total PSA.

Prostate-specific antigen is a protein produced by the prostate gland and released into the bloodstream. A large share of it binds to carrier proteins, while a smaller share remains free. Laboratories measure both fractions and divide the free value by the total value to produce a ratio.

The ratio is most often used as a secondary consideration when a total PSA result falls in an intermediate range. A lower free-to-total percentage has been associated with a greater likelihood of prostate cancer on biopsy, whereas a higher percentage is more often seen with benign prostate enlargement or inflammation.

The result is not a diagnosis on its own. Clinicians interpret it alongside the total PSA, the digital rectal examination, the prostate volume, prior biopsy history, and other clinical findings. Because the ratio is a percentage rather than a concentration, it should be read together with the absolute values from which it was calculated.
